What is Statutory Maternity Pay (SMP)?

Your average weekly earnings must be at least £123 per week
You must give your employer at least 28 days' notice that you want to stop work
You must provide proof of your pregnancy (usually a MAT B1 form from your doctor or midwife)

Important: This calculator provides an estimate only. Your actual SMP may vary depending on your specific circumstances. Always check with your employer or HMRC for confirmation of your entitlement.

When Does SMP Start?

SMP can start from:

The 11th week before your baby is due (at the earliest)
The day after you give birth (if your baby arrives early)
The day after you stop work if you're off work for a pregnancy-related illness in the 4 weeks before your due date

What if I Don't Qualify for SMP?

If you don't qualify for SMP, you might be able to get Maternity Allowance instead. Maternity Allowance is paid for up to 39 weeks and you can claim it if you:

Have been employed or self-employed for at least 26 weeks in the 66 weeks before your due date
Earned at least £30 a week for at least 13 weeks
